Abstract: The phenomenon of self-assembly of atomic and molecular superstructures on crystal surfaces is attracting an increasing interest in nanotechnology. Self-organised nano-templates, where the self-assembled monolayer traps other molecules with selected functional properties, can be used to build large nanoscale structures. Self-assembled superstructures can form chiral domains ranging from 1D chains to 2D monolayers.
There have been many scanning tunneling microscopy (STM) studies of self-assembly of melamine, perylene tetra-carboxylic di-imide (PTCDI) or perylene tetra-carboxylic di-anhydride (PTCDA) molecules on the Au(111) and Ag/Si(111) surfaces. STM images of these networks do not reveal the exact details of the intermolecular bonding and the network growth. Therefore theory can help to determine the exact atomic structure of these networks.
We present a theoretical study of self-assembly of molecular networks formed by…

Liquid Crystals are a state of matter that lies between the classical liquid and solid state. What defines a liquid crystal is the long-range orientation order similar to a solid and the ability to move translationally like a liquid, which provides the ability to change their configuration. There are numerous types of liquid crystals that each have individual properties. Commonly known liquid crystals are nematic, which has a common orientation but no positional ordering, and smetic, which has a common orientation and positional ordering in one direction and random orientation in the other directions. Due…

Today UCLan held its Sunday Open Day. The event was a record in terms of attendance: we had a total of 1,409 prospective students register, eclipsing the previous Open Day record of 1,301 set on 2nd October 2011. Physics lecture room was overcrowded with potential students and their parents, so some extra chairs need to be brought in. Our undergraduate students and postdocs did a great job in showing the teaching laboratories, explaining the experiments and talking to potential students. The staff was trying to keep up with their pace. The next open day is on Saturday, 27th of October 2012.
If you study physics at UCLan come and help out on UCLan’s open day on Sunday, 30th of September 2012. Tell potential students how exciting Physics is !

Collective behaviour of birds, fish, ants, … humans. Is it Physics, Mathematics or Biology ?
by Professor Andrei Zvelindovsky
University of Central Lancashire
Large systems of self-propelling particles (SPP) form a special class of so-called active matter. Examples of such systems found in nature are: flocks of birds, schools of fishes, ants, groups of bacteria, etc. One can often see how these animals develop coherent motion, amazing the observer by the diversity of its forms and shapes. Emergence of collective behaviour in active matter from relatively simple motion of single organisms is on the forefront of modern interdisciplinary research.
On the 19th and 20th of April 2011, the University of Central Lancashire hosted the first British Conference of Undergraduate Research.
